Improving exposure assessment in environmental epidemiology: Application of spatio-temporal visualization tools
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2005-05)
A thorough assessment of human exposure to environmental agents should incorporate mobility patterns and temporal changes in human behaviors and concentrations of contaminants; yet the temporal dimension is often ...
An Incomplete Cholesky Factorization for Dense Symmetric Positive Definite Matrices
(Kluwer Academic Publishers; Swets & Zeitlinger ; Springer Science+Business Media, 2000-09)
In this paper, we study the use of an incomplete Cholesky factorization (ICF) as a preconditioner for solving dense symmetric positive definite linear systems. This method is suitable for situations where matrices cannot ...
CTP: A New Constraint-Based Formalism for Conditional, Temporal Planning
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-10)
Temporal constraints pose a challenge for conditional planning, because it is necessary for a conditional planner to determine whether a candidate plan will satisfy the specified temporal constraints. This can be difficult, ...
Automatic Thematic Extractor
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-07)
We have created a system that identifies musical “keywords” or themes. The system searches for all patterns composed of melodic (intervallic for our purposes) repetition in a piece. This process generally uncovers a large ...
Rational Communication in Multi-Agent Environments
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-09)
We address the issue of rational communicative behavior among autonomous self-interested agents that have to make decisions as to what to communicate, to whom, and how. Following decision theory, we postulate that a rational ...
Analyzing scenery images by monotonic tree
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2003-04)
Content-based image retrieval (CBIR) has been an active research area in the last ten years, and a variety of techniques have been developed. However, retrieving images on the basis of low-level features has proven ...
Quantum Computing with Trapped Ion Hyperfine Qubits
(Kluwer Academic Publishers-Plenum Publishers; Springer Science + Business Media, Inc., 2004-10)
We discuss the basic aspects of quantum information processing with trapped ions, including the principles of ion trapping, preparation and detection of hyperfine qubits, single-qubit operations and multi-qubit entanglement ...
Generalizations of the Hamming Associative Memory
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-04)
This Letter reviews four models of associative memory which generalize the operation of the Hamming associative memory: the grounded Hamming memory, the cellular Hamming memory, the decoupled Hamming memory, and the two-level ...
Automatic Annotation and Retrieval of Images
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-06)
Although a variety of techniques have been developed for content-based image retrieval (CBIR), automatic image retrieval by semantics still remains a challenging problem. We propose a novel approach for semantics-based ...
